I wouldn't say that we ignore the catastrophic events. But we can't accept
any and every claim as valid without some evidence. Looking at the picture
of the crater, reading the account, I have several questions about this
being a crater at all. First, it is 2 miles wide. THat is about twice as
large as Berringer meteor crater in Arizona and that impact would have
killed everything for a large distance. I can't recall the figure, but I
once read that deer in New Mexico would have died from that blast.
Secondly, they speak of a ring inside the bowl shaped depression as being "
a classic feature of meteor impact craters." THis ignores the fact that
multipole ring craters are classic features of only the very largest (many
10s to hundreds of miles wide) craters. This one is too small for a
multiring crater.
Thirdly, if it is a crater, drilling into it should find shock metamorphism
which is the metamorphism of rocks due to high pressure, short duration
events. THere are characteristic mineral fabrics associated with this
phenomenon. That is the sine qua non of meteoric impact, yet I find no
discussion of that
Fourthly, meteor impacts always have what I call splatter and spray. THere
should be a layer of debris and ejecta found far from the crater. Young
craters on the moon have what are called rays, which are lineaments of this
ejecta. I don't see that on the photo.
Fourthly, there is salt in the area and salt domes. Just east of this spot
are some of the most interesting salt glaciers of Iran. How do we know that
this isn't a dissolution collapse feature caused by the dissolution of salt
in an underlying salt dome?

Catastrophic events happen but not everything claimed to be one IS one. We
shouldn't naively believe every claim either.
